need to test different kernel versions to locate the problem. like
kernel-v5.2-rc1/2/3 or v5.1-rc1/2/3 ...

Please test latest mainline kernel:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.2-rc6/

Did you notice a significant delay for booting process when the HDMI and
ac3 can't work? there are 30s delay between #1 and #2. Please check the
dmesg to find why there is a 30s delay when plugging a usb sound card.
